Description
Technical Field
[0001] The utility model relates to the technical field of washing machines, in particular to a drainage tee structure for a wall-mounted washing machine. Background Technique
[0002] A wall-mounted washing machine is a washing machine that can be installed on the wall. It is usually designed to be relatively compact and suitable for living environments with limited space. Compared with traditional floor-standing washing machines, wall-mounted washing machines can save floor space and provide more flexible layout options. The drainage structure of existing wall-mounted washing machines adopts a drainage tee structure. The drainage tee structure of a wall-mounted washing machine is usually used to distribute the water flow discharged from the washing machine to multiple drainage pipes, or to guide the waste water of the washing machine to a suitable drainage system. The washing machine inlet, which is the drainage outlet of the washing machine, is usually connected to one connection port of the tee through a hose. The drainage outlet is the main outlet for discharging waste water into the sewer or sink. The spare outlet can be connected to additional drainage equipment or used as an inspection port during maintenance. The tee structure should be installed under the washing machine or close to the wall for easy connection and maintenance, while ensuring unobstructed drainage. To prevent the backflow of sewage from the sewer, some tee structures are designed with anti-backflow valves or water seal devices. Installing a filter screen at the inlet can effectively prevent hair and debris from entering the drain pipe and reduce the risk of blockage. However, after the wall-mounted washing machine has been used for a long time, the filter screen installed at the drainage outlet of the wall-mounted washing machine will be blocked by a large amount of hair and debris. This hair and debris will affect the normal drainage of the drainage outlet. At this time, the filter screen needs to be cleaned, and some structures of the drainage tee structure need to be disassembled to clean the filter screen, which is inconvenient. For this reason, we propose a drainage tee structure for a wall-mounted washing machine. Summary of the Invention
[0003] The purpose of the utility model is to provide a drainage tee structure for a wall-mounted washing machine, including a pipe body. A drive box is installed through the inside of the pipe body. A stabilizing plate is fixedly installed on the inner wall of the pipe body. The stabilizing plate and the drive box are rotationally connected by a sealed rotating shaft to a rotating rod. The rotating rod rotates through the inside of the filter screen. The filter screen is fixedly installed on the inner wall of the pipe body. A scraper, a propeller and multiple groups of blades are fixedly installed on the outer wall of the rotating rod. A drive assembly is installed inside the drive box.
[0004] The drive assembly includes a moving frame. A motor is fixedly installed on the moving frame. A rotating shaft is rotationally connected to the moving frame through a bearing. The bottom end of the rotating shaft is fixedly connected to the driving end of the motor. The top end of the rotating shaft is fixedly connected to a first gear. The first gear can be meshed with a second gear. The second gear is fixedly installed on the outer wall of the rotating rod. A servo electric push rod is fixedly installed inside the drive box. The telescopic end of the servo electric push rod is fixedly connected to the outer wall of the moving frame.
[0005] Preferably, two sets of guide rods slidably penetrate through the inner side of the moving frame. One end of each guide rod is fixedly connected to a first limit block, and the other end of each guide rod is fixedly connected to a second limit block. Both the first limit block and the second limit block are fixedly installed on the inner wall of the driving box.
[0006] Preferably, the bottom of the scraping plate slidably fits against the top of the filter screen. A plurality of groups of blades are located above the scraping plate, and the propeller is located below the filter screen.
[0007] Preferably, a first cleaning plate and a second cleaning plate are fixedly installed on the outer wall of the rotating rod. The bottom of the first cleaning plate slidably fits against the top of the stabilizing plate, and the bottom of the second cleaning plate slidably fits against the top of the driving box.
[0008] Preferably, two sets of mounting seats are fixedly installed on the outer wall of the pipeline main body. A plurality of threaded holes are provided in both sets of mounting seats.
[0009] Preferably, the pipe opening at the top of the pipeline main body is connected to a connection port, and a plurality of threaded holes are provided in the connection port.
[0010] Preferably, the pipe opening at the bottom of the pipeline main body is threadedly connected to the water inlet end of a water flow check valve, and the water outlet end of the water flow check valve is threadedly connected to one end of a hose.
[0011] Preferably, a spare pipe is connected to the middle part of the pipeline main body.
[0012] Preferably, a valve is installed on the spare pipe.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] When the present utility model is draining water normally, when sewage passes through the propeller, the propeller will rotate under the drive of the water flow. The rotation of the propeller causes the rotating rod to rotate, and the rotation of the rotating rod drives the scraping plate and a plurality of groups of blades to rotate. The rotation of the scraping plate continuously stirs and cleans the hair and sundries attached to the surface of the filter screen, preventing the hair and impurities from blocking the filter screen. At the same time, the rotation of the plurality of groups of blades continuously cuts and crushes the hair and impurities in the water, cutting the hair and impurities in the water into finer substances, so that the crushed hair and impurities can pass through the filter holes on the net and can be discharged normally without causing blockage, eliminating the need for manual disassembly and cleaning of the filter screen. At the same time, the rotation of the rotating rod drives the first cleaning plate and the second cleaning plate to rotate. The rotation of the first cleaning plate continuously cleans the top of the stabilizing plate, preventing hair and impurities from adhering to the top of the stabilizing plate, and the rotation of the second cleaning plate continuously cleans the top of the driving box, preventing impurities from remaining on the top of the driving box.
[0015] When the utility model is in daily use, the moving frame contacts the two sets of limiting blocks II, and the first gear will disengage from the second gear. At this time, the rotation of the first gear will not drive the rotation of the second gear. And in the main pipe body, the water flow will drive the propeller to rotate, and the rotation of the propeller will drive the rotating rod to rotate. Since the first gear does not contact the second gear, the first gear will not hinder the rotation of the second gear at this time, and thus will not hinder the rotation of the rotating rod.
[0016] When there are too many impurities in the water and the rotation of the propeller driven by the water flow cannot achieve the effect of effectively cleaning and crushing the impurities, the servo electric push rod is started at this time to drive the moving frame to move along the two sets of guide rods, so that the moving frame contacts the two sets of limiting blocks I. At this time, the first gear can just mesh with the second gear. Then the motor is started to drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the first gear to rotate. The rotation of the first gear will drive the second gear, and the rotation of the second gear will drive the rotation of the rotating rod. Further, the rotation of the rotating rod will drive the scraper and multiple groups of blades to rotate effectively. At this time, the scraper can effectively clean and stir the hair impurities attached to the upper surface of the filter screen, and the effective rotation of multiple groups of blades can better crush the hair and impurities in the water. At this time, the rotation of the rotating rod will drive the propeller to rotate effectively. The effective rotation of the propeller can accelerate the drainage speed of the main pipe body. The principle is to increase the flow velocity and flow rate by stirring and pushing the fluid. At the same time, the effective stirring of the propeller can disperse the fine impurities passing through the filter screen, thereby reducing the risk of blockage of the water flow check valve and the hose.

Detailed Embodiment
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figure 1 - Figure 3 , the figure shows a drainage tee structure of a wall-mounted washing machine of the present utility model, including a pipe main body 1. A drive box 2 is installed through the inside of the pipe main body 1. A stabilizing plate 3 is fixedly installed on the inner wall of the pipe main body 1. The stabilizing plate 3 and the drive box 2 are rotationally connected by a sealing rotating shaft to a rotating rod 4. The rotating rod 4 rotates through the inside of a filter screen 5. The filter screen 5 is fixedly installed on the inner wall of the pipe main body 1. A scraping plate 6, a propeller 7 and multiple groups of blades 8 are fixedly installed on the outer wall of the rotating rod 4. A drive assembly 10 is installed inside the drive box 2;
[0023] The drive assembly 10 includes a moving frame 1001. A motor 1002 is fixedly installed on the moving frame 1001. A rotating shaft 1003 is rotationally connected to the moving frame 1001 through a bearing. The bottom end of the rotating shaft 1003 is fixedly connected to the driving end of the motor 1002. The top end of the rotating shaft 1003 is fixedly connected to a first gear 1004. The first gear 1004 can be engaged with a second gear 1005. The second gear 1005 is fixedly installed on the outer wall of the rotating rod 4. A servo electric push rod 1006 is fixedly installed inside the drive box 2. The telescopic end of the servo electric push rod 1006 is fixedly connected to the outer wall of the moving frame 1001.
[0024] Two guiding rods 12 penetrate through the inside of the moving frame 1001 in a sliding manner. One end of each guiding rod 12 is fixedly connected to a first limiting block 9, and the other end of each guiding rod 12 is fixedly connected to a second limiting block 11. Both the first limiting block 9 and the second limiting block 11 are fixedly installed on the inner wall of the drive box 2; during use, through the two guiding rods 12, the moving frame 1001 can move stably; when the moving frame 1001 contacts the two first limiting blocks 9, the first gear 1004 can just be engaged with the second gear 1005. At this time, the rotation of the first gear 1004 will drive the rotation of the second gear 1005; when the moving frame 1001 contacts the two second limiting blocks 11, the first gear 1004 will disengage from the second gear 1005. At this time, the rotation of the first gear 1004 will not drive the rotation of the second gear 1005, and in the pipe main body 1, the water flow will drive the rotation of the propeller 7, and the rotation of the propeller 7 will drive the rotation of the rotating rod 4. Since the first gear 1004 does not contact the second gear 1005, at this time, the first gear 1004 will not hinder the rotation of the second gear 1005, and thus will not hinder the rotation of the rotating rod 4.
[0025] The bottom of the scraper 6 slides and fits against the top of the filter screen 5. Multiple groups of the blades 8 are located above the scraper 6, and the propeller 7 is located below the filter screen 5. During use, the rotation of the rotating rod 4 drives the rotation of the scraper 6 and multiple groups of blades 8. The rotation of the scraper 6 continuously stirs and cleans the hair and debris attached to the surface of the filter screen 5, preventing the hair and impurities from blocking the filter screen 5. At the same time, the rotation of multiple groups of blades 8 continuously cuts and crushes the hair and impurities in the water, cutting the hair and impurities in the water into finer substances, so that the crushed hair and impurities can pass through the filter holes on the filter screen 5 and can be discharged normally without causing blockage. It should be noted that both the blades 8 and the filter screen 5 are made of tungsten steel, which has good corrosion resistance and chemical stability. The scraper 6 is made of polytetrafluoroethylene, and polytetrafluoroethylene has excellent corrosion resistance, high temperature resistance and low friction coefficient.
[0026] A cleaning plate one 13 and a cleaning plate two 14 are fixedly installed on the outer wall of the rotating rod 4. The bottom of the cleaning plate one 13 slides and fits against the top of the stabilizing plate 3, and the bottom of the cleaning plate two 14 slides and fits against the top of the driving box 2. The rotation of the rotating rod 4 drives the rotation of the cleaning plate one 13 and the cleaning plate two 14. The rotation of the cleaning plate one 13 continuously cleans the top of the stabilizing plate 3, preventing hair and impurities from adhering to the top of the stabilizing plate 3. The rotation of the cleaning plate two 14 continuously cleans the top of the driving box 2, preventing impurities from remaining on the top of the driving box 2. It should be noted that both the cleaning plate one 13 and the cleaning plate two 14 are made of polytetrafluoroethylene, which has excellent corrosion resistance, high temperature resistance and low friction coefficient. The rotating rod 4, the driving box 2 and the stabilizing plate 3 are all made of tungsten steel, which has good corrosion resistance and chemical stability.
[0027] Two mounting seats 15 are fixedly installed on the outer wall of the pipe body 1. Multiple threaded holes are provided on both of the two mounting seats 15. During installation, the two mounting seats 15 are fixedly installed on the wall through fixing bolts, and then the pipe body 1 is fixedly installed on the wall, thereby stably fixing the entire structure on the wall.
[0028] A connection port 16 is connected to the pipe orifice at the top of the pipe body 1. Multiple threaded holes are provided on the connection port 16. During installation, the connection port 16 is fixedly connected to the drain port of the wall-mounted washing machine through fixing bolts. And during installation, the sealing performance between the connection port 16 and the drain port of the wall-mounted washing machine needs to be handled well. For example, use waterproof tape to completely cover the connection between the connection port 16 and the drain port of the wall-mounted washing machine.
[0029] The pipe orifice at the bottom end of the pipe body 1 is threadedly connected to the water inlet end of the water check valve 17, and the water outlet end of the water check valve 17 is threadedly connected to one end of the hose 18; during installation, the end of the hose 18 away from the water check valve 17 is inserted into the sewer. If necessary, the gap between the hose 18 and the sewer can be filled with polyurethane sealant, which can achieve a good waterproof effect; the water check valve 17 is provided to prevent the sewage in the sewer from flowing back.
[0030] A spare pipe 19 is connected to the middle part of the pipe body 1; the spare pipe 19 is provided to connect additional drainage equipment or serve as an inspection port during maintenance.
[0031] A valve 20 is installed on the spare pipe 19; when the spare pipe 19 is not in use usually, the valve 20 is in a closed state to prevent the sewage in the pipe body 1 from flowing out through the spare pipe 19.
[0032] The working principle of the present utility model: During daily use, when the moving frame 1001 contacts the two groups of limiting blocks two 11, the first gear 1004 will disengage from the second gear 1005. At this time, the rotation of the first gear 1004 will not drive the second gear 1005 to rotate. And in the pipe body 1, the water flow will drive the propeller 7 to rotate, and the rotation of the propeller 7 will drive the rotating rod 4 to rotate. Since the first gear 1004 does not contact the second gear 1005, at this time, the first gear 1004 will not hinder the rotation of the second gear 1005, and thus will not hinder the rotation of the rotating rod 4;
[0033] During normal drainage, the sewage in the wall-mounted washing machine is discharged into the pipe body 1 through the connection port 16. When the sewage passes through the propeller 7, driven by the water flow, the propeller 7 will rotate. The rotation of the propeller 7 drives the rotating rod 4 to rotate, and the rotation of the rotating rod 4 will drive the scraper 6 and multiple groups of blades 8 to rotate. The rotation of the scraper 6 will continuously stir and clean the hair and sundries attached to the surface of the filter screen 5, preventing the hair and impurities from blocking the filter screen 5. At the same time, the rotation of multiple groups of blades 8 will continuously cut and crush the hair and impurities in the water, cutting the hair and impurities in the water into finer substances, so that the crushed hair and impurities can pass through the filter holes on the filter screen 5 and can be discharged normally without causing blockage, and there is no need for manual disassembly and cleaning of the filter screen 5; at the same time, the rotation of the rotating rod 4 will drive the cleaning plate one 13 and the cleaning plate two 14 to rotate. The rotation of the cleaning plate one 13 will continuously clean the top end of the stabilizing plate 3 to prevent hair and impurities from adhering to the top end of the stabilizing plate 3. The rotation of the cleaning plate two 14 will continuously clean the top end of the driving box 2 to prevent impurities from remaining on the top end of the driving box 2;
[0034] When there are too many impurities in the water and the rotation of the propeller 7 driven by the water flow cannot effectively clean and crush the impurities, the servo electric push rod 1006 is started at this time to drive the moving frame 1001 to move along the two groups of guide rods 12, so that the moving frame 1001 contacts the two groups of limit blocks 9. At this time, the first gear 1004 can just mesh with the second gear 1005. Then, when the motor 1002 is started, it will drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 will drive the first gear 1004 to rotate. Since the first gear 1004 meshes with the second gear 1005 at this time, the rotation of the first gear 1004 will drive the second gear 1005, and the rotation of the second gear 1005 will drive the rotating rod 4 to rotate. Furthermore, the rotation of the rotating rod 4 will drive the scraper 6 and multiple groups of blades 8 to rotate effectively. At this time, the scraper 6 can effectively clean and stir the hair impurities attached to the upper surface of the filter screen 5, and the effective rotation of multiple groups of blades 8 can better crush the hair and impurities in the water. At this time, the rotation of the rotating rod 4 will drive the propeller 7 to rotate effectively. The effective rotation of the propeller 7 can accelerate the drainage speed of the pipeline main body 1. The principle is to increase the flow speed and flow rate by stirring and pushing the fluid. At the same time, the effective agitation of the propeller 7 can disperse the fine impurities passing through the filter screen 5, thereby reducing the risk of blockage of the water flow check valve 17 and the hose 18.
[0035] It should be noted that both the motor 1002 and the servo electric push rod 1006 need to be externally connected to a suitable power supply during use, and the control switches of the motor 1002 and the servo electric push rod 1006 are installed on the wall through wire connections. These are all existing mature technologies and will not be described in detail here.
[0036] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
